Alex, While I agree that the use of an EUI-64 network identifier predicates a 64-bit prefix, I am not convinced that an EUI-64 is the best way to go. After all, the Ethernet MAC address is only 48 bits, so we are essentially throwing away 16 bits (assuming that the identifier is globally unique).

I speculate that one possible reason for this was to design a SLAAC over Ethernet that is reliable, simple, universal and straightforward to implement. BINGO. And those are all (IMHO) Good Things. In a way, I see SLAAC to have become so popular as opposed to DHCP. Were DHCPv6 more developed
